Why CT Scans are the Go-To Tool
CT scans are highly sensitive and specific, making them a reliable option for detecting large bowel obstructions. They help distinguish between small and large bowel obstructions and identify if the cause is malignant or benign. Their accuracy is crucial for determining the right treatment path.
What a CT Scan Reveals
A CT scan can show a transition point where the colon is dilated and the obstruction begins. It can also reveal whether the obstruction is due to a tumor or other causes like volvulus. This detailed view helps doctors plan effective treatments.
Are There Alternatives?
While plain X-rays are less expensive, they are not as accurate as CT scans. Barium enemas are rarely needed due to the high accuracy of CT scans. Choosing the right imaging method is essential for a correct diagnosis.
